Abstract

Available processing algorithms to extract stripmap SAR images are able to deal with spaceborne case rather than airborne case, because of atmospheric and platform trajectory disturbances. Flight path information should be provided to the processing unit to compensate motion deviations. Motion Compensation through navigation data is usually done in two steps and doesn't change the standard form of the traditional algorithms. Adding Motion Compensation to the approximate – k algorithm is not so easy and similar to other algorithms. It requires major changes in the standard form of the algorithm and has not been done so far. This modification is the main goal of this article. In this paper, we propose a modified form of approximate – k algorithm which is capable to consider Motion Compensation, unlike the traditional form. To evaluate the performance of the proposed algorithm, a set of simulated data and real raw data of ISRCSAR system are applied. Comparision of the extracted images indicates the high performance of the proposed algorithm.
